概括
植物,古老的植物,在保护工作中被严重忽视. 超过一半的评估物种受到威胁,这突显出迫切需要针对性的战略来保护全球生物多样性.
科学领域:
- 植物学 植物学
- 保护生物学 保护生物学
- 生态生态学 生态生态学
背景情况:
- 全球生物多样性评估不成比例地关注脊椎动物和开花植物.
- 类植物 (,肝,角),代表着超过2万个物种的古老植物谱系,在保护研究和评估中显著不足.
- 这种监督对全球生物多样性和生态系统功能构成重大风险.
研究的目的:
- 量化全球保护框架内植物物种低估程度的程度.
- 确定具有高植物多样性和潜在威胁的关键区域和海拔模式.
- 在全球和区域范围内分析植物灭绝风险的主要驱动因素.
主要方法:
- 全球分布记录,海拔数据和国际自然保护联盟 (IUCN) 红色名单数据集的整合.
- 对研究趋势的分析和对影响植物的威胁的元分析.
- 鉴定了37个丰富的植物区域,并检查了全球的海拔模式.
主要成果:
- 只有1.5%的植物物种被IUCN红色名单评估.
- 在评估的植物中,超过50%受到威胁,几乎是植物的全球平均水平的两倍.
- 农业和气候变化是主要的全球威胁,区域差异包括森林砍伐 (非洲,南美洲) 和入侵物种 (欧洲).
结论:
- 植物目前的保护状况被严重低估,对全球生物多样性目标构成重大威胁.
- 紧急实施有针对性的,特定于区域的保护战略是必要的,以缓解加速的植物衰退.
- 如果未能解决植物保护问题,将危及至关重要的生态系统功能和服务.

What is Conservation Biology?
24.7K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations
17.6K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Threats to Biodiversity
27.6K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Non-vascular Seedless Plants

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

What is Biodiversity?
34.5K
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.
